Designed truncated tetrahedron for fun, almost exactly equal edges length, off by probably a few decimals.

Designed truncated tetrahedron for fun, almost exactly equal edges length, off by probably a few decimals.

A truncated tetrahedron is classified as an Archimedean solid, characterized by its geometric structure.

A Releaux tetrahedron

[Reuleaux tetrahedron](https://en.wikipedia.org/wiki/Reuleaux_tetrahedron)

Tetrahedron with Braille (4 sides)

The Reuleaux Tetrahedron is a geometric shape formed by the intersection of four balls with identical radii placed at the vertices of a regular tetrahedron. Each ball's spherical surface passes through the other three vertices, resulting in curved...

I started with the Top Plane. The first tool I used was the polygon with the parameters of 3 faces. Smart dimension the polygon to 100mm then exit sketch You want to click features, reference geometry drop down arrow, plane the top plane and...

Tried to get only a four faced pyramid, but couldn't get it right.

2D tools I used were smart decision and center line.3D tools I used were extrude base and made it draft outwards 29 degree

A Three-Dimensional Figure Composed of a Pyramid Base and Three Rectangular Faces Meeting at a Vertex.

For amusement, a mere piece of metalwork is requested.

I used the polygon tool to make a triangle then used the extrude boss/base tool to make it into a tetrahedronMass = 22.56 gramsVolume = 3090.91 cubic millimetersSurface area = 1529.15 square millimeters

This is an inverted pyramid - a 3-sided pyramid, to be precise. ...You can turn it right-side up, if that's what suits your fancy.

I first started with the polygon tool and narrowed it to 3 sides 55mm each. I than made a plane on top of that triangle which was calculated amount (aprox 41.91mm)from the triangle base, after the plane was made i made a sketch on top and put a point...
